i think Beans was just pointing out that traveling and exercising are hobbies and not extracurricular activities. an extracurricular is typically some organized activity done in a group that someone else can vouch for you that you were there if necessary
if you want to list these things under extracurriculars its your app and your choice, i went to Egypt last summer and am leaving for Europe soon and did not put that on my app because it was for leisure and i didnt feel that it fit in the app, but that was my decision
if your traveling was done in a specific study abroad program you could put it under academic enrichment as it might be a better fit that way
